The watermark data are essentially embedded in the middle band of the DCT domain to make a tradeoff between visual degradation and robustness. The proposed schemes are simple and no original host image is required for watermark extraction. The algorithm also features the capability of embedding multiple orthogonal watermarks into an image simultaneously. A set of systematic experiments, including Gaussian smoothing, JPEG compression, and image cropping are performed to prove the robustness of our algorithms.","PeriodicalId":6422,"journal":{"name":"2000 IEEE International Symposium on Circuits and Systems.

The main idea behind the Young-Wong algorithm [1999] is to determine the boundary information of each module in a floorplan by traversing the corresponding normalized Polish expression from right to left once. By carefully examining each of the three types of moves adopted by the Young-Wong algorithm for generating a new normalized Polish expression, we observe that it is very likely that only a subset of modules might have the boundary information changed in the new normalized Polish expression, and hence only the boundary information for those modules needs to be recomputed. Based on the observation, we improve the Young-Wong algorithm by providing methods to accelerate the boundary information computation.","PeriodicalId":6422,"journal":{"name":"2000 IEEE International Symposium on Circuits and Systems.
